Study on Drilling of Woven Sisal and Aloevera Natural Fibre Polymer Composite

Abstract

Natural fibre reinforced polymer composites are the materials formed by a matrix and a reinforcement of natural fibre. Natural fibre reinforced polymer composites are light in weight, economical, low density, high specific strength, modulus relative no abrasiveness, ease of fibre surface modifications wide availability and are available in variety of forms. They have low densities, comparable material properties, and high moulding flexibility and are environmental friendly. By modifying either the resin system or the natural fibre, natural fibre composites can be designed for different applications ranging from products of commodity to aerospace applications. In this work composite laminate was prepared with natural fibre such as sisal and aloevera with epoxy resin using hand layup technique. The present investigation is an attempt to study the factors that influence the delamination of drilled sisal and aloevera natural fibre reinforced composites using (ɸ 6mm, ɸ 8mm, ɸ 10mm) carbide tip drill bit. Surface roughness test and delamination is carried out on drilled natural fibre composites.
